Japanese expectations for green building assessments

The background and feedback on the Green Building Challenge '98 process in Japan is provided by a representative from one of two Japanese teams (representing the Building Constructors' Society), The positive process of validating and adapting the international criteria to particular national circumstances and then customizing these criteria is explained. Three significant benefits to the Japanese building industry are discussed: existing technologies and methodologies were validated, it was discovered that these have potential for world-wide application, the life expectancy of Japanese buildings needs to be lengthened. Future expectations from Japan include: the ongoing refinement of the international framework for the environmental assessment of buildings; the customization of criteria requires further structure and limits, a critical review of the customization process; an expansion embracing both developed anti developing nations' new and existing buildings, The prototype green building assessment from GBC '98 has the potential to be refined and adopted as a world-wide methodology and is endorsed as the fastest way to achieve world-wide consensus.
